Here's how I solved this for now: I've kept around my 10yo dumb 32'' TV from Samsung for casual viewing, like showing a video to our kid (we hardly every use it otherwise). For something serious I made a beamer cart that I can roll everywhere, with a PS4, a Nintendo Switch, and a place to put a laptop. Beamers can mostly still be had without any connectivity. A decent 1080p one from BenQ costs you around 600-700 bucks and that's plenty enough for me to have full bluray quality movie experiences. For sound I just bought an Avantree AptX low latency bluetooth receiver, and I plan on extending this with an HDMI audio splitter and low latency transmitter with optical input to get full stereo quality on a nice pair of speakers. Screw surround, screw 4K, keep your 3D crap, I'm getting too old for this.
A 700USD beamer to protect your privacy? Surely you can just broadcast your computer on to the tv?
Get a receiver with HDMI passthrough so the sound comes out your hifi speakers and the video signal gets sent on to the TV. No need for bluetooth, splitters, optical input
it's not just to protect my privacy, it's just generally how I've come to think about consuming media in my house.
* a beamer gives you a viewing angle as wide as you'd want to have in a cinema (wider than this is uncomfortable).
* therefore immersion in movies and games is about the strongest you can have for non-VR content in your home.
* cinema is (a) rarely showing what I want anymore and (b) incovenient now that we've got a small kid, so this solves that as well.
* a beamer on a cart is mobile - sometimes I just roll it to the end of our bed, lie down and play Zelda or whatever for half an hour to relax a bit.
* beamers are mostly still dumb, so there's not much to break that I cannot fix and not much to annoy me, like "go online to get the full experience (and our ads)" and all that crap.
* when we're done the beamer can be rolled out of sight, so you don't have a giant black hole in the middle of your living room, constantly telling you you should probably do something with it to make it worthwhile.
* setting up the beamer is a bit of an act, and that's good, so we do it about once every week and have enough activities in our life other than passive media viewing. with the cart it's still quick enough to not be very inconvenient, I can just plug in one power cable and push a couple of buttons and it's done.
Is beamer quality decent? Every time I've seen one in action (I admit last time was years ago) it was nowhere near the quality of TV and the room also needed to be very dark.
When the bulbs break they're quite pricey to replace no?
It depends on how you want to use it. With good lighting conditions it totally is, and this matches the way in which I use our beamer quite well (during the day there's no time anyways). If you want something that works during the day and rolling down blinds is too annoying for you, then yes, it's not the best choice. But beamers have become much better than 5-10y ago for a given price. DLP technology has become affordable for high resolutions and its rainbow effect has been treated quite effectively, giving you very sharp images. Strong light bulbs are also much more prevalent. Yes you gotta replace them, but I'm anticipating many years until I run out of their 1000+ hours of lifetime, and 150 bucks or so every couple of years seems quite fine for me, more realistically it's probably going to be a new device every 5-10 years like with TVs.
